Answer:

astenosphere

Explanation:

The mesosphere and the astenosphere are both part of the mantle. The mesosphere is the deeper part, while the astenosphere is the outer part of the mantle. Both of these layers have the same chemical composition, but the temperature and pressure are different in them. The mesosphere has higher temperature and pressure, so even though it is very hot, the rock is actually solid. The astenosphere has lower temperature and pressure, so the rock is more liquid.

3. This happens through an external pollinator resulting in a diversity of species.  

4. This is a very special case where the flower attracts the insect to mate with bright petals, odor, and the shape.  

5. These types depend on ants and other insects to get pollinated.

6. Here, the pollens release some kind of force, when an insect gets in contact with anther which results in getting away the agent from the flower.
